Hi guys...I recently upgraded my tank to 40 gallons from 15 gallons. I have two angels, two red tail sharks, a gourami, a Black Skirt Tetra and five tiger barbs. All these fishes were in the 15 gallons tank and were co-existing very peacefully, and they are doing so in the new 40 gallon tank too. The new tank setup has been almost a month. I recently added three blue auratus cichlids which are very small, about an inch or so. Will all of them co exist as these three cichlids grow up?
